Duct fitting SpiroFlex SpiroFlex 80 connection T-piece SX-PEL80T

SpiroFlex 80 connection T-piece SX-PEL80T is a metal duct fitting intended for creating a T-shaped junction between three circular ducts with a nominal diameter of 80 mm. The fitting provides a rigid branch for ventilation and air distribution systems, enabling air to be split or redirected in compact residential and light commercial HVAC installations. It is manufactured for compatibility with 80 mm circular ducts and supports straightforward integration into existing duct runs where a durable metal junction is preferred.

Advantages

The T-piece is made of metal to ensure dimensional stability and resistance to deformation under normal operating conditions. Its circular connection profiles match standard 80 mm ducts, which simplifies installation and reduces the need for additional adapters. The compact T-shaped design minimizes space requirements at junction points while maintaining consistent airflow paths for more predictable system performance.

Suitable for

• Residential ventilation branch connections
• Light commercial HVAC systems requiring compact duct junctions
• Air distribution and redirection between main and branch ducts
• Retrofit projects where a rigid metal T-connection is preferable

Key specifications

• Material: metal construction suitable for HVAC duct applications
• Nominal connection diameter: 80 mm for all three ports
• Shape: T-piece for one main run and one perpendicular branch
• Compatibility: designed for 80 mm circular duct systems
• Application: ventilation and air distribution junction

How to use

Position the T-piece at the required junction point and align each 80 mm duct end with the corresponding port. Ensure duct ends are clean and free of obstructions before inserting. Secure the connection using the appropriate clamps, sealant, or fasteners recommended for metal ductwork to maintain airtight joins. After installation, verify that airflow direction and distribution meet system design by checking for leaks and proper sealing at the connection points.

Usage recommendations

Use the SpiroFlex 80 connection T-piece in systems sized for 80 mm ducts and avoid forcing mismatched diameters without a proper adapter. For optimal performance, combine with compatible clamps and sealing tape or mastic to prevent air loss and reduce noise. Inspect joints periodically for corrosion or loosening in environments with elevated humidity or mechanical vibration.
